Pricing
FreemiumJetBrains AI offers four tiers. AI Free is $0/month with 3 AI credits every 30 days, unlimited code completion via JetBrains' Mellum model, and local model support via Ollama or LM Studio, but excludes frontier models and Junie for sustained agentic work. AI Pro is $10/month (Individual) or $20/month (Business), with 10 AI credits per month. AI Ultimate is $30/month (Individual) or $60/month (Business), with 35 AI credits per month, including a $5 bonus over the plan price. AI Enterprise is custom-priced at roughly $60/user/month billed annually, adding organization-wide credit pooling and enterprise controls. Each AI Credit equals $1 USD, and unused top-up credits (purchased separately at $1 each) remain valid for 12 months, while unused monthly plan credits do not roll over. A 30-day AI Pro trial is available for new users. AI Pro is also bundled into JetBrains' All Products Pack and dotUltimate subscriptions.
FreemiumVibe Free offers limited access to Mistral's SOTA models, web and mobile access, limited messages, web searches, and coding sessions, image generation, and 100+ connectors. Vibe Pro is $14.99/month with more messages, web searches, more complex task handling, all-day coding in the CLI, IDE, and web, more image generations, and chat and email support. Team is $24.99/user/month, adding up to 30GB of storage per user, domain name verification, and data export. Enterprise offers custom models, custom agents, custom workflows, audit logs, SAML SSO, and white-labeling via a private deployment, priced on request. A Student plan offers Vibe Pro for $5.99/month for verified students. Separately, the API is billed per million tokens: for example Mistral Large 3 costs $0.5 input / $1.5 output, Medium 3.5 costs $1.5 input / $7.5 output, and Small 4 costs $0.15 input / $0.6 output, with batch processing available at a 50% discount and Enterprise APIs available at a 75% premium for regional controls, SLAs, and premium support.

Summary
AI coding assistance built natively into every JetBrains IDE
Frontier open-weight AI models and the Vibe agent for work and code
JetBrains AI Assistant Pros & Cons
Pros
- Deep semantic project understanding via IntelliJ's existing static-analysis engine, not just open-file context
- Junie autonomous agent handles multi-file planning, implementation, and self-correction, including a dedicated Debug mode
- Works across a single subscription spanning 20+ JetBrains IDEs
- Supports local models via Ollama and LM Studio at zero credit cost
- Strong enterprise trust features including zero-data-retention policies and .aiignore support
Cons
- Locked into the JetBrains IDE ecosystem, so it offers no value for developers using VS Code or other editors
- Credit-based quota system can be confusing, and heavy Junie or Claude Agent use can exhaust monthly credits well before the billing period ends
- AI Pro's 10 monthly credits are reportedly consumed within about a week under heavy agentic use, pushing users toward costly top-ups ($1 per credit)
- Best suited to JVM languages (Java, Kotlin); completion quality is reportedly less consistent for other languages
- AI Free tier excludes frontier models and the Junie agent, limiting it mostly to a demo of completion features
Mistral AI Pros & Cons
Pros
- Owns its full model stack end-to-end rather than reselling third-party models
- Open-weights even flagship models, giving businesses genuine self-hosting flexibility
- EU-based hosting and self-hosted options are a strong fit for data-sovereignty-sensitive customers
- Vibe unifies chat, work automation, and coding into one agent and one subscription
- Competitive API pricing, especially on cost-efficient models like Small 4 and Ministral
Cons
- Recent rebrand from Le Chat to Vibe (May 2026) may cause confusion for existing users and search results still reference the old name
- API pricing spans 32+ models with different rates per capability, requiring careful reading to estimate true costs at scale
- Commercial self-hosted deployment of open-weight models requires a separate Mistral license beyond the Apache 2.0 research terms
- Smaller ecosystem and community size compared to OpenAI or Anthropic, despite strong open-weight momentum
- Enterprise APIs carry a 75% premium over list pricing on select models for regional data controls and premium support
